Project Car - Supercharge Your '05 To '10 Mustang

By , Photography by

When the '05 S197 Mustang arrived, it appeared on every 8x10 square piece of advertisement short of a Wheaties box. It looked right, sounded right, and seemed like the ultimate solution to the weird-ish New Edge SN-95s that preceded it. Then, ouch, the 4.6 3V only made 300 hp and 330 lb-ft, and the convertible version weighed around 3,600 pounds. The car had everything but speed.

Six years later, there are plenty of these Mustangs just waiting for modification. We snagged an '06 GT and added a set of '10 SVT 19x9.5-inch wheels, 295/30ZR19 Toyo Proxes 4 tires, and a Mustang GT handling pack with SVT brakes.

Now the car is nearly glued to the road and looks killer, but the horse- power war has raged on and 300 hp now comes with the economy, six- cylinder version of just about everything on the road. Our Mustang is no match for LS-powered fifth-gen Camaros or even newer versions of the Mustang GT. Is there no justice? Yes, there is, and it comes from Whipple Superchargers and Ford Racing.

The Options

Ford makes it easy by offering only two supercharger systems for the '05 to '10 3V Mustang GT. The 400hp kit comes with a 2.3L (140-cid) Whipple twin-screw supercharger and all the hardware to get it on the car. If it is installed by a Ford dealer, it will hold the car's warranty. The 550hp Big Boost kit comes with a smaller pulley, an air-to-water intercooler, special calibration, and a new dual fuel pump. The kits are for manual Mustangs only. If you have an automatic, there is a 475hp version for you.

The blower packages are more than just a bunch of parts that happen to fit together. Ford tested them on an engine dyno to map all the engine parameters before subjecting the engine to full power pulls from 30 to 110 degrees F. Then the engines go into a car where they are similarly brutalized in a climate-controlled, wind- tunnel dyno, where hundreds of pulls are made to simulate changes in elevation, air quality, and temperature. Then the cars are driven more than 4,000 miles. This is all to get a calibration validation and a 50-state-legal EO number. For a well-tested, street-legal 550 hp that you just bolt on, it's hard to beat the price.

Badass

Punch it and you get that slide-whistle shriek and plenty of smoke and fun with the traction control off. (Shhhhh, if you don't stomp it open, the boost bypass makes the car act and sound like a stock, 300hp GT.) Midrange torque is excellent, so there are no cars you can't pass and there is no lane you can't own. We think the traction control is a bit of a mother hen, however, when it cuts the throttle on bumpy roads at WOT and limits the rpm to 6,375, even with the glee button in the Off position. We curse it when we are in the mood for mayhem and thank it when we have to commute on Monday morning and nothing is broken.

At this point the car feels fast enough to get into trouble, but that doesn't stop us from wanting to go faster. To do so, we need more cam, more heads, and enough connecting rod to handle 7,500 rpm. These parts exist in the form of the Aluminator. It is a short-block with a forged Cobra rotating assembly and forged 8.5:1 pistons. Adding the ported heads and hot rod cams would easily push us over the 500-rwhp mark, likely to the detriment of the drivetrain and catalytic converters. We recommend the Aluminator swap and Big Boost kit. You won't be disappointed.
